Step 1: In Firefox, click Tools then select Options.
Step 3: Uncheck the box that says “Move or resize existing windows“.
That’s it! Those pesky websites won’t be able to resize your browser window anymore. Make sure to check out the rest of our articles about Firefox!Image credit: Mixy Lorenzo (seriously, how good does that cupcake look?)
